Key Components:

• Time Dial: The large central dial used to set the current time and program on/off cycles.
• Trippers: Small, non-removable pins around the time dial that are pushed in or pulled out to set specific on/off times.
• Manual Override Switch: A small switch, typically located on the top or side, allowing you to manually turn the connected appliance on or off, overriding the programmed settings.
• Outlet Receptacle: The socket on the timer where you plug in your lamp or appliance.

Setup

1. Set Current Time: Rotate the large central dial clockwise until the current time aligns with the "TIME OF DAY" indicator arrow. The dial is marked with AM and PM hours.
2. Program ON/OFF Times: The dial has small, non-removable trippers around its circumference. Each tripper represents a specific time interval. To set an "ON" time, push the corresponding tripper(s) inward. To set an "OFF" time, pull the corresponding tripper(s) outward. The timer allows for 48 on/off settings per day.
3. Plug in Timer: Insert the timer into a standard 120V wall outlet.
4. Connect Appliance: Plug the lamp or appliance you wish to control into the outlet receptacle on the timer.

Operating

Automatic Operation:

Once the current time is set and the on/off trippers are programmed, the timer will automatically turn the connected appliance on and off according to your settings. The dial will continuously rotate, advancing the time.

Manual Override:

The timer is equipped with a manual override switch. This switch allows you to temporarily turn the connected appliance on or off, regardless of the programmed settings. Be aware that on some models, using the manual override switch may advance the internal time setting. If you notice the programmed times shifting, re-verify and reset the current time as needed.

Maintenance

• Cleaning: Unplug the timer from the wall outlet. Wipe the exterior with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
• Storage: If storing the timer for an extended period, unplug it and keep it in a cool, dry place away from direct sunlight.
• Inspection: Periodically inspect the timer and its cord for any signs of damage, such as frayed wires or cracked casing. If damage is found, discontinue use and replace the unit.

Troubleshooting

  • Ensure the timer is securely plugged into a live outlet.
  • Verify the appliance is properly plugged into the timer and is in working order.
  • Check that the current time is correctly set on the dial.
  • Confirm that the ON/OFF trippers are correctly pushed in or pulled out for the desired times.
  • Ensure the manual override switch is not in a position that is overriding the programmed settings.
